A brief summery: The child has grown too old for toys and now only a hand full of lego men remain. They must escape or face death but there are those whose who will stop at nothing to halt the escape.

Plot: As a child objects can be seen as living things due to imagination. It is this that gave life and souls to the toys. They have lived a life of bliss and immortality. Since the child (or giant one as is the toys' name for the child) sees them as living things, if a toy should die the child can bring them back to life by a mere glance. Thusly the toys live their lives sticking to rules and laws which have kept them safe.
But things are changing. The child has grown up. The time the toys have feared and talked about has come. The child no longer sees them as living beings but lifeless objects. Now if the child sees a toy their life leaves at once. The time known to the toys as "the great clean up" has happened. Only a handful of lego men remain, small and able to hide unseen. They know they must leave before they are seen and meet their doom.
It is not so simple. There are still some who do not except that the end has come and will stop at nothing to make sure that no one disobeys the toy rules layed down long ago.
This film follows the actions of the last group to attempt their escape from the room and thus the house.
